The particular Claude Monet Water Lilies painting shown is located at the Art Institute of Chicago, not in Paris.

There is a reason Daryl has not been stabbing walkers when there is only a few at a time. Since these walkers have acid in their blood getting close to them is riskier as they can burn with a simple touch, plus it would likely degrade the blade of a knife. Also with access to black powder rifles ammo isn't as scarce, as black powder is fairly easy to make.

Monet's Water Lillie panting is actually a series consisting of at least 200 known paintings, some are in private collections, others in museums and art galleries. While there are a few on display at the Art Institute of Chicago there are about two dozen of these paintings on display in Paris at the Musée Marmottan Monet and the Musée d'Orsay.

The images of Jim Morrison's grave are incorrect. His grave is at ground level, not raised up, and there is a large tomb right in front of it, not a fence and it can be seen only at a distance from the path.

Daryl fired the rifle at the Walker in the opening of the episode. At this stage of the franchise, Daryl should have been fully aware of the fact that gun fire would attract other Walkers. The task could have easily been accomplished through the use of a sharp weapon, especially since the Walker was in close proximity.
